How do I unclog my bathroom sink?
Just get a bottle of liquid Drano. Use half the bottle, wait 20 minutes and pour hot water down it. If it needs it, then use the other half of the bottle in it. This usually breaks up old toothpaste and gunk that builds up.
You can use a plunger.
take the plummers wrench and d disconnect the pee trap pipe..The U shaped pipe under neith..Drain it with bucket and snake..
